Has anyone used Deltawalker?

I have a quick question. I just bought a new Apple PowerBook and have moved my images(thousands) from my old machine to the new one. I want to verify that all the images got to the new one. I found a program called DeltaWalker that will do a folder/file compare and let me verify that all the files made it. Has anyone used this application? I am trying to figure out if it will work for what I need befor dropping the $40.
